SEWING-MACHINE CABINET.

SPECIFICATION forming part of Letters Patent No. 561,087, dated June 2,1896.

Application filed December 22. 1893. Serial No. 494,388. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL F'BROWN, of the city and county ofProvidence, in the State of Rhode Island, have invented certain new anduseful Improvements in Sewing-Machine Cabinets; and I do hereby declarethe following specification, taken in connection with the accompanyingdrawings, forming a part of the same, to be a full, clear, and exactdescription thereof.

The invention relates to cabinets for sewing-machines of that class inwhich the machine may, when not required for use, be lowered from itsoperative position and housed within the cabinet, and when it is to beused may be raised into operative position and there supported for use.

The object of the invention is to provide a cabinet which will be simplein construction,

convenient, and easy of operation, and in which the machine when raisedinto position for use will be held in such position without the aid oflocking devices.

To that end the invention consists in the combinations and arrangementsof parts hereinafter described.

Referring to the drawings, Figure 1 is a rear elevation of my improvedcabinet with the back of the casing removed to show the construction andshowing the sewing-machine in its housed position. Fig. 2 is acorresponding rear elevation showing the sewing-machine in its elevatedposition for use. Fig. 3 is a vertical tranverse section on the line asm, Fig. 1. Fig. 4 is a rear elevation showing the cabinet closed. Figs.5 and 6 are details of parts of the operating mechanism and showing saidparts in different positions. Fig. 7 is a section on the line y y, Fig.6; and Fig. 8 is an enlarged section on the line to w, Fig. 1.

The cabinet consists of an inclosing case A, in the top a of which is anopening through which the sewing-machine B may be raised or lowered.Said sewing-machine is mounted upon and secured to a movable platforma,which said platform is supported by brackets 12, said brackets being inturn secured to a slide 0, fitted to slide in the inclined ways d, asshown in the drawings.

The mechanism for raising and lowering the sewing-machine is as follows:To the case A is hinged a swinging cover O. Secured to the rear of thecase A is a bracket f, to which bracket is pivoted at g one end of abellcrank lever g. One end of a link h is pivoted at h to the slide a,and the other end of said link is pivoted at 71 to the bell-crank leverg, thereby connecting said slide with said lever and forming atoggle'between the case A and the platform a. To the free end of thebellcrank lever 9 one end of a link 11 is pivotally connected, the otherend of said link being pivoted to one end of a lever 70, the other endof said lever being pivoted to-the cover 0. A slot is cut in the top aand in the cover O to receive the lever 70 when said cover is open, asshown in Fig. 2. A block is is preferably secured to the case, as shownin Fig. 2, to serve as a fulcrum for the lever 70, although, if desired,said lever may fulcrum upon the top of the adjacent side wall of thecase. This block 70, when employed, may be rigidly secured in place; butI prefer to make it vertically adjustable at the point where the lever kbears upon it, as shown in Fig. 8, and so that the upper edge of saidlever, when the cover O is open, may be made to come flush with theupper surface of the top a. For the purpose of adjustment the link i ispreferably connected to the bell-crank lever g by an adjustableconnection, as shown in the drawings. If desired, a spring m, attachedat one end to the case A and at the other end to the bell-crank lever g,maybe employed to assist or-make easy the first movement of the cover 0in opening; but said spring is not necessary. To support the cover 0 inits open position a hinged or jointed lever e is pivoted at one end tothe cover 0 and at the other end to the side of the case A, the end ofone leg of said hinged lever resting, when the cover is open, upon theblock Z, secured to the case, as shown in Fig. 2. The treadle n andfly-wheel 0 may be secured to the bottom and side of the case A,

respectively, and an opening is to be provided 5 in the position shownin Fig. 1., the cover 0 being closed. If it be desired to elevate themachine into position for use, all that is necessary to be done issimply to take hold of the cover C and turn it over into the positionshown in Fig. 2. By this movement of the cover and by means of thelever-and-link connection between said cover and the slide 0 said slidewill be moved up the ways (1, thereby raising the sewing machine upthrough the opening in the top a and bringing the supporting-platform aup into a position flush with the top a and so as to oceupy the openingtherein, the parts being then all in the position shown in 2. It will beobserved that with the parts in this position the toggle formed by thelever g and the link it is straightened and the three pivots g, h, and71. of said toggle are brought into nearly a straight line. By thisarrangement the sewing-machine will be sufficiently supported in itselevated position without the employment of any belts or other lockingdevices for the purpose. To lower and house the machine, all that isrequired is simply to return the cover 0 to its closed position, thereturn movement of the cover permitting the slide 0 to slide down theinclined ways, thereby lowering the machine and its supporting-platform,the inclination of the ways serving to carry the machine in its descentclear of the fly-wheel 0. By adjusting the connection between the link iand bell-crank lever g the upward movement of the platform a may bereadily adjusted so as to bring the top of said platform up flush withthe top of the case, and by constructing the brackets b so as to projectfront and rear somewhat beyond the platform a the projecting portions ofsaid brackets will serve as stops to limit the upward movement of theplatform, as shown in Fig. 3.

It will be seen that by the arrangement of parts above described thereis a direct me chanieal connection between the hinged cover of thecabinet and the sewing-machine and that this connection is composedentirely of a series of levers and links, forming a continuouslever-and-link connection, and that the arrangement and organization aresuch that there is no lost motion whatever, but each and every part ofthe movement of the cover is accompanied by a corresponding movement ofthe machine. It will also be observed that the only manipulationrequired is the simple opening and closing of the cover and that theopening of said cover not only serves to raise the machine into positionfor use, but causes it to be held in such operative position as againstany pressure that will be brought upon it in use.

The cabinet above described, while especially designed for asewing-machine, may be employed for any macl1ine-such as a typewriter,for instance-which it is desired to have at times supported in operativeposition and at other times housed within the cabinet.
